Founded in 1979, Activision was the first ever third party software company
for the Atari 2600. Established by four disgruntled Atari employees, Activision
produced some of the best games for the 2600 and other systems as well. They
began the trend of crediting programmers with the creation of games and offered
patches
to players who earned high scores. Activision
is still very alive today, and has even produced updates to their classic Pitfall!,
as well as releasing retro packs of old Atari games.
